Does Calcium Carbonate Cause Kidney Stones? Harvard Study Debunks Long-Standing Misconception!

At 72 years old, Zhang Ma suffered from persistent back pain and numbness in her hands and feet. A medical check-up revealed severe osteoporosis, and her doctor advised her to take calcium supplements. However, after less than a week of taking calcium carbonate tablets, she stopped—worried that they might cause kidney stones, based on what her neighbor told her. But is this really true?

For years, many people have believed that excessive calcium intake leads to kidney stones, as calcium is a primary component of these stones. However, a study by Harvard University suggests that this may be a misunderstanding!

The Truth About Calcium and Kidney Stones

Research shows that adequate calcium intake actually reduces the risk of kidney stones. This is because oxalates, naturally found in vegetables and other foods, can bind with calcium in the intestines to form calcium oxalate, which is then excreted in the stool.

However, if calcium intake is too low, excess oxalates get absorbed into the bloodstream and are later excreted through the kidneys—increasing the risk of kidney stones.

The Right Way to Take Calcium

Taking water-soluble calcium supplements in the correct way, especially with meals, can improve calcium absorption while reducing urinary calcium excretion, thus helping prevent kidney stones. Doctors recommend osteoporosis patients consume 1,000-1,200 mg of calcium daily, along with vitamin D to enhance absorption.
